After very busy last few weeks with JUDCon
(checkout my Hot Rod presentation here
) and JBoss World/Red Hat Summit
(check out my presentation with Manik Surtani here
and the REST for Clouds one here
), we’re proud to release Infinispan 4.1.0.CR1, the first candidate release of the Infinispan 4.1 series. The release is downloadable in the usual place
. A lot of work has gone into this release primarily with the aim of stabilising new functionality wrote in previous beta/alpha versions. Here are some of the highlights included in this release:

Enable Hot Rod servers to run behind a proxy
in environments such as EC2, and make TCP buffers and TCP no delay flag configurable for both the server and client.

Important performance improvements for Infinispan based Lucene directory and Hot Rod client and sever.

To avoid confusion, the single jar distribution has been removed. The two remaining distributions are: The bin distribution containing the Infinispan modules and documentation, and the all distribution which adds demos on top of that.

A more detailed changelog can be found here.

Finally, if you’re a user of Infinispan 4.0 or 4.1, please make sure you download and try this release out so that any outstanding issues are fixed in time for the final release.
